There is overflow in the following code
int x = int.MaxValue;
Console.WriteLine(x + x + 1L); //prints -1
Whereas in the following code there is no overflow
int x = int.MaxValue;
Console.WriteLine(x + 1L + x); //prints 4294967295

Command line arguments parsing is Go is very similar to other languages. In you code you just access slice of arguments where first argument will be the name of program itself.

Using the document-ready event can have small performance drawbacks, with delayed execution of up to ~300ms. Sometimes the same behavior can be achieved by execution of code just before the closing </body> tag:

You can create a task (Console Command) in Laravel using Artisan. From your command line:
php artisan make:console MyTaskName
This creates the file in app/Console/Commands/MyTaskName.php. It will look like this:
<?php
namespace App\Console\Commands;
use Illuminate\Console\Command;
c...
You can make a task available to Artisan and to your application in the app/Console/Kernel.php file.
The Kernel class contains an array named $commands which make your commands available to your application.
Add your command to this array, in order to make it available to Artisan and your applicat...
When your command is made available to your application, you can use Laravel to schedule it to run at pre-defined intervals, just like you would a CRON.
In The app/Console/Kernel.php file you will find a schedule method that you can use to schedule your task.
<?php
namespace App\Console;
...
The scheduler can be run using the command:
php artisan schedule:run
The scheduler needs to be run every minute in order to work correctly. You can set this up by creating a cron job with the following line, which runs the scheduler every minute in the background.

It is common for an AsyncTask to require a reference to the Activity that called it.
If the AsyncTask is an inner class of the Activity, then you can reference it and any member variables/methods directly.
If, however, the AsyncTask is not an inner class of the Activity, you will need to pass an A...
If your team is following a rebase-based workflow, it may be a advantageous to setup git so that each newly created branch will perform a rebase operation, instead of a merge operation, during a git pull.
To setup every new branch to automatically rebase, add the following to your .gitconfig or .gi...
To change the URL of the repository you want your remote to point to, you can use the set-url option, like so:

Use quasiquotes to create a Tree in a macro.

std::optional<float> divide(float a, float b) {
if (b!=0.f) return a/b;
return {};
}
Here we return either the fraction a/b, but if it is not defined (would be infinity) we instead return the empty optional.
A more complex case:
